DRUG DESCRIPTION

Hepatitis B Immune Globulin (Human)

BayHep B® (hepatitis b immune globulin human) treated with solvent/detergent is a sterile
solution of hepatitis B hyperimmune immune globulin for intramuscular
administration; it contains no preservative. BayHep B (hepatitis b immune globulin human) is prepared by cold
ethanol fractionation from the plasma of donors with high titers of antibody to
the hepatitis B surface antigen (anti-HBs). The immune globulin is isolated
from solubilized Cohn Fraction II. The Fraction II solution is adjusted to a
final concentration of 0.3% tri-n-butyl phosphate (TNBP) and 0.2% sodium
cholate. After the addition of solvent (TNBP) and detergent (sodium cholate), the
solution is heated to 30°C and maintained at that temperature for not less than
6 hours. After the viral inactivation step, the reactants are removed by
precipitation, filtration and finally ultrafiltration and diafiltration. BayHep
B is formulated as a 15–18% protein solution at a pH of 6.4–7.2 in 0.21–0.32 M glycine.
BayHep B (hepatitis b immune globulin human) is then incubated in the final container for 21–28 days at 20–27°C.
Each vial contains anti-HBs antibody equivalent to or exceeding the potency of
anti-HBs in a U.S. reference hepatitis B immune globulin (Center for Biologics
Evaluation and Research, FDA). The U.S. reference has been tested against the
World Health Organization standard Hepatitis B Immune Globulin and found to be equal
to 217 international units (IU) per mL.

The removal and inactivation of spiked model enveloped and
non-enveloped viruses during the manufacturing process for BayHep B (hepatitis b immune globulin human) has been
validated in laboratory studies. Human Immunodeficiency Virus, Type 1 (HIV-1),
was chosen as the relevant virus for blood products; Bovine Viral Diarrhea
Virus (BVDV) was chosen to model Hepatitis C virus; Pseudorabies virus (PRV)
was chosen to model Hepatitis B virus and the Herpes viruses; and Reo virus
type 3 (Reo) was chosen to model non-enveloped viruses and for its resistance
to physical and chemical inactivation. Significant removal of model enveloped
and non-enveloped viruses is achieved at two steps in the Cohn fractionation
process leading to the collection of Cohn Fraction II: the precipitation and
removal of Fraction III in the processing of Fraction II + IIIW suspension to
Effluent III and the filtration step in the processing of Effluent III to
Filtrate III. Significant inactivation of enveloped viruses is achieved at the
time of treatment of solubilized Cohn Fraction II with TNBP/sodium cholate.

What are the precautions when taking hepatitis b immune globulin (human) (BayHep B)?

Before receiving hepatitis B immune globulin, tell your doctor or pharmacist if you are allergic to it; or had a previous reaction to other immune globulins; or if you have any other allergies.

PRECAUTIONS: Before receiving hepatitis B immune globulin, tell your doctor or pharmacist if you are allergic to it; or had a previous reaction to other immune globulins; or if you have any other allergies. This product may contain inactive ingredients, which can cause allergic reactions or other problems. Talk to your pharmacist for more details.

This drug may make you dizzy. Do not drive, use machinery, or do any activity that requires alertness until you are sure you can perform such activities safely. Limit alcoholic beverages.

This medication is made from human blood. Even though the blood is carefully tested, and this medication goes through a special manufacturing process, there is an extremely small chance that you may get infections (such as hepatitis A) from the medication. Consult your doctor or pharmacist for more information.

Some immune globulin products are made with maltose. This substance can cause false high blood sugar levels when your blood sugar is normal or even low. If you have diabetes, check with your doctor or pharmacist whether the product you are using contains maltose and whether your blood sugar testing supplies will work with this product. Rarely, serious problems have occurred when too much insulin was given because of false high sugar readings or when low blood sugar went untreated.

Tell your doctor of any recent/planned vaccinations. This medication may prevent a good response to live virus vaccines (such as measles, mumps, varicella). If you are vaccinated less than 14 days before receiving this medication or during the 3 months after receiving this medication, you may need to be vaccinated again or tested to see whether the vaccine was effective.

During pregnancy, this medication should be used only when clearly needed. Discuss the risks and benefits with your doctor.
